Analog Devices Inc. ADM6713MAKS-REEL7

Overview

ADM6713MAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing open-drain active-low RESET output with 4.38 V threshold, 140 ms minimum timeout, 12 μA supply current, and operation down to 1 V VCC for monitoring 3 V/3.3 V systems in portable embedded applications.

For engineers reviewing the ADM6713MAKS-REEL7 datasheet, ADM6713MAKS-REEL7 pinout, ADM6713MAKS-REEL7 application, or ADM6713MAKS-REEL7 equivalent, key selection criteria include reset threshold accuracy over −40°C to +125°C, manual reset debounce timing, power supply glitch immunity up to 100 ns, and compatibility with external pull-up voltages higher than VCC.

Technical Context

The ADM6713MAKS-REEL7 integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, and debounced manual reset input with 1 μs minimum pulse width acceptance and 100 ns glitch rejection. Its reset generator asserts RESET low during VCC ramp-up until VCC exceeds 4.38 V (typ) and sustains it for ≥140 ms after threshold crossing.

As an open-drain device, ADM6713MAKS-REEL7 requires an external pull-up resistor-enabling interface with logic families operating at voltages independent of VCC-and maintains valid RESET assertion down to VCC = 1 V, with leakage current ≤1 μA when deasserted.

FAQ

What is the exact reset threshold voltage of ADM6713MAKS-REEL7 and how does it vary with temperature?

The ADM6713MAKS-REEL7 has a nominal reset threshold of 4.38 V at 25°C, with tolerance of ±0.07 V (4.31 V to 4.45 V). Over −40°C to +85°C, the threshold ranges from 4.25 V to 4.50 V, and from 4.20 V to 4.56 V at 85°C to +125°C. Its temperature coefficient is specified at 30 ppm/°C, ensuring predictable drift across its full operating range.

Does ADM6713MAKS-REEL7 require an external pull-up resistor on the RESET pin, and why?

Yes, ADM6713MAKS-REEL7 requires an external pull-up resistor on the RESET pin because it features an open-drain output stage. This architecture allows the RESET signal to interface with logic systems operating at voltages different from VCC - for example, pulling RESET up to 1.8 V or 5 V - and avoids contention when multiple devices share a common reset bus. A typical value is 10 kΩ to VCC or another compatible rail.

How does the manual reset (MR) input behave on ADM6713MAKS-REEL7 during and after activation?

When the MR pin on ADM6713MAKS-REEL7 is pulled low (≤0.3 VCC), the RESET output immediately goes low and remains low for 240 ms (typical) after MR returns high. The input rejects glitches shorter than 100 ns and guarantees recognition of pulses ≥1 μs. If left unconnected, MR floats high and has an internal 10–20 kΩ pull-up, so no external resistor is needed unless noise immunity is required.

What is the minimum VCC voltage at which ADM6713MAKS-REEL7 can still assert a valid RESET signal?

ADM6713MAKS-REEL7 asserts a valid active-low RESET signal down to VCC = 1.0 V. Below this, the internal circuitry cannot guarantee sink capability. For operation down to VCC = 0 V, a 100 kΩ pull-down resistor from RESET to GND is recommended to prevent floating logic states during complete power loss.

Is ADM6713MAKS-REEL7 RoHS compliant and what is its packaging format?

Yes, ADM6713MAKS-REEL7 is RoHS compliant (indicated by the "Z" suffix in alternate part numbers like ADM6713MAKSZ-REEL7). It is supplied in tape-and-reel format per EIA-481 standard, with 3,000 units per reel (REEL7 designation), in a 4-lead SC70 (KS-4) package measuring 2.2 mm × 1.35 mm with 0.5 mm lead pitch.
